The Guardian article nailed it, thanks!
It doesn’t cite exactly where they got the Greenpeace photo from, but I found it here: https://media.greenpeace.org/archive/Climate-Impact-Documentation-in-Norway--Svalbard-27MZIF4WNED.html
Climate Impact Documentation in Norway, Svalbard Greenpeace documentation showing that glacier “Blomstrandbreen” has retreated nearly 2 km since 1928, with an accelerated rate of 35 metres lost per year since 1960 and even higher in the past decade. In the image, view of climate campaigner Truls Gulowsen on a speed boat going to a mine in Longyearbyen.

A bit more from the Guardian article:
Greenpeace activists visited the glacier last weekend on the Rainbow Warrior taking pictures from the same locations to highlight the effects of global warming, which the group says is a threat to the future of the planet.
The Blomstrandbreen glacier has retreated by one and a quarter miles since 1928, according to Greenpeace. It was shrinking by 115ft a year in the 1960s, a rate which has risen.
Recent studies carried out by US researchers and reported in Science last month said that 85% of the glaciers they examined had lost vast portions of their mass in the last 40 years.
Keith Echelmayer of the University of Alaska at Fairbanks, who has carried out research into Alaska’s ice streams and checked glacier thickness, said: “Most glaciers have thinned several hundred feet at low elevation in the last 40 years and about 60 feet at higher elevations.”
